This invention relates'to a loader for material onto wagons or other conveyances,

Figure 2 is a rear elevation, partly in section, illustrating Referrmg 1n detail to the drawings, the nuframe and is located substantially intermediate A draft hitch 8, in the form of an elongated fr ame, is hinged or pivoted partly in the main frame of the loader 'I'he forward ends of the members 9 are converged and Dlin character i7. v

A connecting rod I8 is pivoted to the control lever and to a bell member 8 adjacent the rear end of the latter. The bell crank lever is pivctally connected to a bracket 20 secured on the main frame. By varying the position of the control lever, the main frame may be caused to plvot on the ground wheels, the purpose of which 1s to vary the receiving veyor 2l with relation to e gathering conveyor extends downwardly and forwardly held against 32 secured to said shaft 29.

crank lever I9 pivotally mounted on the draft endless apron material into a vehicle 33 traveling alongside of the loader.

The conveyors 2l and 25 each include an endless apron 34 supported by rollers 35 and one of the rollers has a sprocket gear 3E connected thereto. The sprocket gear Bt is located on the conveyor 2l while one of the rollers of the conveyor 25 has a pulley 3l secured thereto. The 3d of the conveyors 2i and 25 have secured thereto and arranged transversely thereof flight-forming elements :it each presenting a hook shaped portion and a coiled portion 3Q. The coiled portions 39 tension the hook shaped portions. The hook shaped portions are adapted to engage with the material and cause the latter to travel with the upper run of the endless aprons of the conveyors 2l and 225.

It is to be understood that the material discharges from the gathering conveyor into the clelivery conveyor, as shown in Figure 3, and is discharged from the delivery conveyor into the wagon or like conveyance, as shown in Figure 2.

A power shaft fl@ is journaled in bearings li carried by the main frame e and the draft member 8 and is composed of a plurality of sections coupled by universal joints t2. One of the sections of the power shaft has a splined connection with one of the universal joints so that said power shaft may automatically lengthen and shorten to compensate for the tilting of the main frame relative to the'draft member Zi. The forward end of the power shaft is coupled to the power taireoff of the tractor. The power shaft lil drives a shaft d3 iournaled on the main frame by a sprocket chain lll .and sprocket gears d5. The shaft i3 extends into a gear box it and is geared to a shaft mi. A sprocket chain @B trained over a sprocket gear i9 secured on the shaft il drives the endless apron of the conveyor trained over the sprocket gear $6. A pulley 5B is secured to the shaft i3 and a belt 5l connects the pulley 5l! to the pulley 3l. The runs of the belt 5I are crossed, as clearly shown in Figures 1 and 2. Thusfit will be seen that power derived from the tractor, may be employed for driving the conveyors 2| and 25, the conveyor` 2l acting to gather the vines from the windrows and deliver them into the conveyor 25 which discharges the vines into the wagon or conveyance 33.

A draft hitch 5d is pivotally mounted on the draft member 8 and may be coupled to the draft tongue 55 of the wagon 33 so that the wagon will be made to travel alongside of the loader, the

2l by boing A and coupled to a power casamos tractor acting to pull both the loader and the wagon as well as to drive the conveyors.

Thus it will be seen that vegetation raked in vwindrows may be rapidly and easily gathered by this device and delivered into a wagon or similar conveyance, all under the power of a tractor, consequently saving time in which to gather such material and reduces to a minimum the amount of manpower necessary to carry out such Work.

While I have shown and described the pre ferred embodiment of my invention, it will 'ce understood that minor changes in construction. combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

In a loader, a tiltable main frame 'of substantially rectangular shape, a pair of ground wheels supporting said frame, gathering and delivering conveyors pivotally mounted on the frame 'with the gathering conveyor extending downwardly and forwardly of the frame and laterally of one of the ground wheels and disposed over the other ground wheel, an elongated draft frame having one end pivoted on the main frame substantially in alignment with one of the ground wheels and laterally of the gathering conveyor and having the forward end contracted and coupled to a tractor, a power shaft journaled on the frame take off of the tractor and including sections joined by universal joints and one of the sections having a slidable drive connection with one of the joints, a drive means connecting the shaft to the conveyors, a and lowering means for the delivery conveyor, means yieldably supporting the gathering conveyor for movement on its pivot when engaging an obstruction, a manually operated lever mounted for pivotal movement on the forward `end of the draft frame. a bell crank lever pivotally connected to the main frame and pivotally mounted on the rear end of the draft frame, a connecting link pivotally connecting the control lever to the bell crank lever whereby through the manipulation of the control lever the main frame may be tilted on the ground wheels, and a draft member pivoted to one side of the draft frame and coupled to a vehicle for pulling the latter in a position under the discharge end of the dclivery conveyor.
